cis-polyisoprene
polymerCis-polyisoprene is a natural or synthetic rubber polymer characterized by its flexible chain structure with cis-configuration double bonds, making it chemically identical to natural rubber. It is widely used in automotive tires, seals, gaskets, and vibration-damping applications where resilience, elasticity, and low-temperature flexibility are critical; engineers select it over synthetic alternatives when natural sourcing is preferred or when specific dynamic properties and fatigue resistance are required for cyclic loading applications.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
